Yes in most cases, a written offer, even without a company chop and signature, can be considered legally binding. If this is from a T1/T2 company I would not worry. Warm regards, Frederic 

Hi there,

More important than the legal aspects, which depend on the country's legal framework for labor law, is the fact that top firms generally honor their word and certainly contracts (even w/o chop and signatures).

I've not heard of a single case where a firm changed their mind like that. They don't just hand out contracts like cookies you know - just to exceptionally bring and talented people like yourself :)

Well done and relax!

Hi there,

Congratulations on the offer! In terms of your question:

Q: I have received a written offer but without a company chop and signature yet. Is this written offer already “legal binding”? 

Whether is legally binding might depend on the local regulation so it is difficult to comment. Eventually, in most countries you should get an offer with a signature/stamp, which from your comment it seems they will provide regardless.

I don't think you have to worry. If you want to be 100% sure, you can just avoid to withdraw from other processes until you have the copy with the signature.

Best,

Francesco

More than “legal binding” it is “reputation binding”. 

As such, only in extreme situations will top consulting firms back out from an offer they made. Usually they farthest they'll do is to postpone starting date.

The moment both parties sign it.

But in terms of reputation-binding for a top-tier firm, when they send the offer and you sign.

Realistically, it's once they receive your acceptance and signed copy. Legally, once there is a counter-signed copy
